Grounded Neural Networking: Modeling Complex Quantitative Data

The latest advances in artificial intelligence software (neural networking) have finally made it possible for qualitative researchers to apply the grounded theory method to the study of complex quantitative databases in a manner consistent with the postpositivistic, neopragmatic assumptions of most symbolic interactionists. The strength of neural networking for the study of quantitative data is twofold: it blurs the boundaries between qualitative and quantitative analysis, and it allows grounded theorists to embrace the complexity of quantitative data. The specific technique most useful to grounded theory is the Self‐Organizing Map (SOM). To demonstrate the utility of the SOM we (1) provide a brief review of grounded theory, focusing on how it was originally intended as a comparative method applicable to both quantitative and qualitative data; (2) examine how the SOM is compatible with the traditional techniques of grounded theory; and (3) demonstrate how the SOM assists grounded theory by applying it to an example based on our research.     

Case-based methods and agent-based modelling: bridging the divide to leverage their combined strengths

Two leading camps for studying social complexity are case-based methods (CBM) and agent-based modelling (ABM). Despite the potential epistemological links between ‘cases’ and ‘agents,’ neither camp has leveraged their combined strengths. A bridge can be built, however, by drawing on Abbott’s insight that ‘agents are cases doing things’, Byrne’s suggestion that ‘cases are complex systems with agency’, and by viewing CBM and ABM within the broader trend towards computational modelling of cases. To demonstrate the utility of this bridge, we describe how CBM can utilise ABM to identify case-based trends; explore the interactions and collective behaviour of cases; and study different scenarios. We also describe how ABM can utilise CBM to identify agent types; construct agent behaviour rules; and link these to outcomes to calibrate and validate model results. To further demonstrate the bridge, we review a public health study that made initial steps in combining CBM and ABM.     

Predicting 2-year marital satisfaction from partners' discussion of their marriage checkup

This study tested whether the observed marital interactions of partners following a marriage checkup predicted marital satisfaction 2 years later. In addition, this study examined whether recommendations to pursue therapy predicted subsequent treatment seeking and whether changes in marital distress following the checkup remained stable over 2 years. Results suggest that the affective tone of a couple's interaction predicts later marital satisfaction. Further, receiving a treatment recommendation predicted subsequent treatment seeking for wives. Finally, support was found for the hypothesis that changes in marital distress are self-sustaining.     

Does culture matter for the economic performance of countries? An overview of the literature

From the point of view of economic development, the world is far from being homogeneous. Among the possible causes of such uneven evolution, culture is starting to attract the attention of a growing number of scholars. The present paper surveys some of the most important contributions on culture and economics, with a particular focus on the definition and measurement of culture and on the impact of different cultural traits on economic variables. According to this review of the literature, cultures emphasising individual effort while providing equal opportunities for everyone are more likely to encourage sustained economic growth.     

New directions for management accounting

Using a general systems rationale, this paper develops a theoretical structure for approaching the problem of management accounting. The management control problem is explicated in terms of maintaining a relationship between the enterprise's structure and its environment. An enterprise's structure is composed of three elements (and their inter-relations): a decision and control subsystem; a financial funds subsystem and an operating (physical transforms) subsystem. Portrayed in these terms, the problem of management accounting is shown to require a methodology which is able to take cognizance of economic, sociological, psychological and other aspects of the enterprise system. The model described here provides a general intellectual frame of reference for ordering the problem.     

Alfred Schutz and Herbert Simon: Can their Action Theories Work Together?

This paper combines Alfred Shultz and Herbert Simon's theories of action in order to understand the grey area between dynamic and completely unstructured decision making better. As a result I have put together a specific scheme of how choice elements are represented from an agent's personal experience, so as to create a bridge between the phenomenological and cognitive‐procedural approaches of decision making. I first look at the key points of their original models relating Alfred Schutz's “provinces of meaning” and Herbert Simon's “satisficing” mechanism. I then consider the particular concept of intentionality and reasoning by analogy for different choice settings. Finally I have suggested a perspective based on creative behaviour and sense‐making for ill‐structured conditions.     

Neuropathology in Alzheimer's disease: awaking from a hundred-year-old dream

For one hundred years after Alois Alzheimer's first report of Alzheimer's disease (AD) in 1906, the pathological hallmarks of the disease, senile plaques and neurofibrillary tangles (NFTs), have been attractive targets for researchers. Therefore, not surprisingly, efforts to understand disease mechanisms have concentrated on the cell biology of amyloid-beta (Abeta) deposition as senile plaques or on the phosphorylation and aggregation of tau as NFTs. However, it now appears that this focus on pathology as a central contributor to disease may be misguided. Indeed, neurons associated with Abeta and NFTs in AD brain show a decrease in oxidative damage relative to those in vulnerable but morphologically intact areas of the brain, suggesting that neurodegenerative lesions are compensatory phenomena, and thus manifestations of cellular adaptation. That Abeta and tau accumulations indicate an age-related physiological reaction to chronic stress calls into question the rationale of current therapeutic efforts targeted toward lesion removal. Moreover, if this concept holds true for pathology in other neurodegenerative diseases, we may need to restructure our thinking and undergo a paradigm shift before substantial progress can be made in therapeutic intervention.     

Researching social care for minority ethnic older people: implications of some Scottish research

Summary The paper explores issues raised by research on patterns ofwelfare and mutual care among older Pakistani people and theirfamilies, with particular reference to their use, or lack ofuse of social care services. Qualitative interviews were conductedwith (self-defined) minority ethnic older people, professionalsin statutory services and in minority-led community-based groups.The organization of services is discussed, with special referenceto issues of power and control, the role of the voluntary (non-profit)and statutory sectors, the debate regarding the possible needfor specialist versus generic services, and the role of minority-ledinitiatives. Secondly, issues of service staffing are examined,and the dangers of marginalizing minority services and staffreviewed, especially with reference to divisions of labour inservice provision and staff's own perspectives. Thirdly, themethodological implications of the work are explores, includingissues of linguistic and cultural communication and workingwith relatively powerless social groups, whose views are sought.Examining the views of professional social care workers is alsoproblematized, with reference to their gate-keeping role. Itis argued that user perspectives are essential to the developmentof appropriate services for minority ethnic groups. In conclusion,the need to raise these issues in other work is discussed.     

The unseen protagonists. Ecuadorians’ daughters between Ecuador and Southern Europe

Scholars consider Latin American migration toward Europe to be a case study in the feminization of international migration. However, these studies have not focused on second-generation girls. Beginning from a gender and intergenerational approach, this paper stresses the agency role played by the reunified teenage daughters of Ecuadorian migrants both in Ecuador as well as in Southern Europe. The discussion is based on two transnational ethnographic studies conducted with Ecuadorian children aged 13–18 and their families in two medium-sized Southern European cities, Genoa and Seville, and in Ecuador between 2008 and 2011. First, the paper shows that girls carry out an essential task as caretakers in the transnational household, both in the point of origin and destination. Despite these responsibilities, they show a higher commitment to school, both in terms of time spent in school and their results. Secondly, it analyses how girls negotiate their role both inside and outside of the family, challenging the parents’ moral and sexual control strategies. The results disclose an identity struggle in the everyday lives of these girls: they participate in the migration project of the transnational family, but simultaneously they implement practices of resistance and renegotiation addressing the traditional division of gender roles.     

Reputational cues in repeated trust games

The importance of reputation in human societies is highlighted both by theoretical models and empirical studies. In this paper, we have extended the scope of previous experimental studies based on trust games by creating treatments where players can rate their opponents’ behavior and know their past ratings. Our results showed that being rated by other players and letting this rating be known are factors that increase cooperation levels even when rational reputational investment motives are ruled out. More generally, subjects tended to respond to reputational opportunities even when this was neither rational nor explainable by reciprocity.
